Auditors:

Test Plan:

Plan 1

1. enable wallet
2. close preference page
3. visit some pages (stay on this pages more then 15s), some of the verified as well (for example clifton, coinmarket, ddg, etc)
4. open preference page and go to payments
5. make sure that all sites that should be verified are verified (to trigger table refresh just visit another site)

Plan 2

1. enable wallet
2. every hour there should be call to the server to get publisher timestamp

Reviewer Checklist:

Tests

• Tests should be independent and work correctly when run individually or as a suite ref

Do we need to call clearInterval and set to false when payments is turned off?

[NejcZdovc]

it's just for safety, because we trigger boot via action, so there could be race problem if we trigger interval in other place

[NejcZdovc]

fixed base on our slack conversation

s/mulitple/multiple 😄

[NejcZdovc]

fixed

[bsclifton]

Two items noted (concern about clearing interval and misspelling)

Changes work great as expected- Code changes look good too 😄 👍

Would be nice to have getPublisherTimestamp return if payments is disabled... but that is an edge case which seems pretty minimal (and would only happen once an hour until closed).
